"I'm wondering if anyone out there has experience with the 4K footage the DJI Phantom 3 produces and how it works with YouTube. If so, do you have any suggested export settings to get the most resolution out of the footage - without having to buy a new server farm. Does YouTube support the footage natively, or does it have to be converted first?"

Shooting the 4K movie with the DJI Phantom 3 and you wanna upload the Phantom 3 4K video to YouTube for sharing. However, something let you down; YouTube's server keeps rejecting the Phantom 3 file. Got more details of the Phantom 3 recorded videos and I got know the Phantom 3 recordings are in MOV wrapper encoded with MPEG-4 AVC/H.264 up to 4K resolution.

To get 4K footage from DJI Phantom 3 to YouTube, there are two basic issues we need to resolve: divide 4K files into shorter 15 min sections ( YouTube has a 15 min limit in usual.); convert Phantom 3 H.264 MOV to a more compatible file type like AVI for YouTube. Another important, adjust the video bitrate, frame rate for your 4K video before putting to YouTube.

Although there are numbered tools and utilities can convert and compress 4K videos, few of them can process at a fast speed. Featured with the most advanced converting technology, Pavtube Video Converteris now providing the most reliable and professional 4K solutions to all format issues including 4K XAVC/XAVC S, 4K MP4, 4K MTS, 4K MXF and more.

Step 1: Download and have a quick installation. The trial version will have a watermark on your converted files. Except for that, there are no time limitation, no virus, and no unnecessary bundle apps while downloading. After that, click "Add Video" button to load your original videos. You can load several files at once thanks to "Add from folder" button.

Step 2: Here, you need to choose what you want the output to be. Click "Format" drop-down list, and then select "HD Video>>AVI HD Video (*.avi)" as the best output format.

Step 3: You can also press the "Settings" button to adjust the video size, bitrate, frame rate, audio sample rate, etc to optimize the quality. As far as I know, YouTube's maximum 4K bitrate is 45Mbps and it doesn't work with 60fps 4K video well. You can set the video frame rate like 24fps. And keep in mind, YouTube always recompress the uploaded video, so upload the best, highest resolution you can.

Step 4: When everything is done, you can take a preview by hitting "Play" button. If you are satisfied with the final result, you can click "Convert" button to finish the conversion work.

Conclusion: Once the conversion process is complete, you can click "Open Folder" button to get the generated files for uploading DJI Phantom 3 4K video to YouTube with optimum performance.
